PUMP VALVE.

.Application filed May 13,

T 0 all whomc't may concern:

Be it known that I, JAMES W. SANDLIN,

a citizen oi. the United States, residing at Humble, in the county of Harris and State 5, of Texas, have invented certain new and i useful Improvements in a Pump Valve, ot

which the following is a specification.

This invention relates to new and useful improvements in a pump valve. n

One object of the invention is to provide, in a pump, a rotatable valve which ispro vided to control the flow oi' fluid through the pump and so constructed that it will agitate the sand settling around it to preo vent the clogging of the valve.

Another object is to provide a valve which will be positively and eifectively rotated, while the pump is in operation, so that the sand will be kept in agitation and will be o kept clear of the valve seat so thatthe valve will not become clogged and will always seat perfectly to prevent back How ofA fluid.

lVith the above and other Objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts, and example of which is given in this specication and illustrated in the accompanying drawings, wherein A Figure l is a vertical sectional view.

Figures 2 and 3 are transverse sectional views of the upper and lower cages, respectively.

Figures 4 and are plan and sectional views, respectively, of a spider employed.

Figure 6 'hows a side view, partially insection, of a guide employed.

Figure 7 is a side view of the valve.

Figure 8 shows a side view of the valve actuating wings.

Figure 9 is a thereof, and

Fig. 10 shows another form of valve rotating means.

Referring now more particularly to the drawings, the numeral 1 designates a sleeve, upon the upper end of which the valve cage 2 is screwed, and clamped between them there is the reversible valve seat 3 located within the cage. This cage is open, having the side slots 4. (3o-operating with the seat there is a ball valve 5 having a central vertical opening, throu h which the stem 6 of the head 7 exten s. The upper end transverse sectional view 1921. Serial No. 469,159.

oi' this stem is threaded. The numeral 8 designates a guide whose lower end has a` threaded socket which is screwed onto said threaded end ot the stem. This guide works through a central bearing 9 of the spider 10. This spider is clamped between the upper end of the open cage 1l which is threaded 'I0 end of the cage 2 and the lower f thereon. The upper end of this last `mentioned cage is reduced and outwardly threaded for the attachment of a separate rod thereto, through which the pump is operated.

The head 7 has the vspiraled wings l2 radiating therefrom, against which the fluid, passing through the pump, operates to rotate the wings and the valve 5.

The entire construction hereinabove described constitutesvwhat is commonly known as the traveling valve of a pump. As tlie same is reciprocated downwardly the fluid passes up through the seat 3 and in passing upwardly operates against said wings and rotates the valve 5. Upon up-stroke the i fluid above said valve is forced on up through the discharge pipe of the pump. 4The rotation of the wings l2 and valve 5 will agitate the sand and prevent it from settling into and clogging the seat, and said sand will pass through said cages and settle back. into the bore or pass on out with the Huid. The valve 5 will thus at all times seat perfectly and the back flow of fluid will be prevented.

The different parts of the structure being detachable, the same may be readily assembled or taken apart and the parts readily repaired or replaced.

In Figure 10 the stem depending` fromy the valve is shown with a. helical fin 13 which may be employed as an alternative means for rotating the valve.

1. A pump valve including a seat, an upwardly opening ball valve mounted thereon, a stem fitted through said valve, a plurality of spiraled tins formed integrally with the lower end of said stem, a cage fitted over said seat and confining said valve, a spider in. said cage above the valve having a central bearing, a guide rod Awhose lower end is threaded over the upper end of the stem and abuts against the said valve and 2. A pump Valve mechanism including a seat, an upwardly opening` valve above the seat, e cage confining the valve, a spider iXed in the cage above the Valve and formed with a central bearing, a stem littedfthrough said valve, a' guide rod Working through Said bearing Whose ylower end is formed into a clamp nut which is threaded onto the up-k per end of the stein and abuts 'against the valve to secure said stem to the valve, and a JAMES WV.
